need all 15 formulas (—,—)

no spam , 2morrow exam !!

be fast , don't be lazy !!

15 formulas = 15 points​

Answer 1

Answer:

(L = Length, B = Breadth, H = Height, R = Radius)

1) Total Surface area of Cuboid = 2(LB+BH+LH)

2) Leteral surface area of Cuboid = 2(L+B)×H

3) Volume of Cuboid = L×B×H

4) Total surface area of Cube = 6a²

5) Leteral surface area of Cube = 4a²

6) Volume of Cube = a³

7) Total surface area of Cylinder = 2πR(R+H)

8) Lateral surface area of Cylinder = 2πRH

9) Volume of Cylinder = πR²H

10) Total surface area of Cone = πR(L+R)

11) Lateral Surface area of Cone = πRL

12) Volume of Cone = ⅓×πR³

13) Total surface area of Sphere = 4πR²

14) Lateral surface area of Sphere = 4πR²

15) Volume of Sphere = 4/3×πR³

Answer 2

Answer:

(L = Length, B = Breadth, H = Height, R = Radius) =

1) Total Surface area of Cuboid = 2(LB+BH+LH)

2) Leteral surface area of Cuboid = 2(L+B)xH

3) Volume of Cuboid = L×B×H

4) Total surface area of Cube = ба?

5) Leteral surface area of Cube = 4a?

6) Volume of Cube = a 3

7) Total surface area of Cylinder = 2TR(R+H)

8) Lateral surface area of Cylinder = 2TRH =

9) Volume of Cylinder = TR2H

10) Total surface area of Cone = TR(L+R)

11) Lateral Surface area of Cone = TRL

12) Volume of Cone = 13XTR3

13) Total surface area of Sphere = 4TTR?

14) Lateral surface area of Sphere = 4TTR?

15) Volume of Sphere = 4/3×TR³
